Application filed. April 30, 1908. Serial No. 430,138.

To all whom it may concern:

Be it known that I, GEORGE L. MOVEY, a citizen of the United States, residing at \Valden, in the county of Orange and State of New York, have invented certain new and useful Improvements in Pocket-Knives; and 1 do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to pocket-knives provided with catches for holding their blades in their open and closed positions; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

in the drawings, Figure 1 is a longitudinal section through a knife constructed according to this invention, showing the blade closed. Fig. 2 is a similar view showing the blade open. Fig. 3 is a plan view partly in section. Fig. 4 is a side view with one of the outer side-plates removed. Fig. 5 is a side view of the locking-plate drawn to an enlarged scale, and showing the adjacent parts in section.

A are the metallic inner side-plates or lining-plates of the handle, and B are the outer side-plates of celluloid or other ornamental material.

C is the distancepiece between the plates A, and c are the rivets which hold the said parts securely connected together.

I) is a tubular pivot secured to the plates A, and E is a knife-blade mounted on the pivot 1). Two similar pivots and blades are provided, one at each end of the handle, but only one is shown as they are both alike.

F is the main-spring or opening-spring for the blade. This spring is secured to the middle part of the handle in any approved manner, and it engages with the shank of the blade near its pivot.

Two holes, notches or recesses (Z and e are provided in the shank of the blade, and G is a spiingcatch provided with a pin 9 which is slidable in a hole g in one of the plates A, and which engages with the holes (Z and e. The spring-catch G is secured to the outside of one of the plates A in a chamber 6 in one of the outer side-plates B, and it is provided with a hole h which works over one of the rivets c. The spring-catch is secured to the plate A by a single screw or rivet H, and I is a reinforcing spring also secured to the said plate by the same screw H. One end portion of the spring I overlaps one end portion of the spring-catch, and it has an inclined portion 2' at its other end which bears against the plate A.

J is a releasing-pinwhich is slidable in the tubular rivet, and which engages with the free end portion of the spring-catch. A finger-button j is provided on one end of the pin J and its other end has an enlargement which engages with a countersunk end portion of the hole in the tubular pivot so that the pin will not drop out. The reinforcing spring I makes the spring-catch more satisfactory in its action, without being hard to press back.

The spring-catch G holds the blade in its opened and closed positions, and when retracted by the pin J, the blade can be opened or closed. The blade is opened automatically by the mainspring F, and is closed by hand.

In order to prevent the releasing-pin from being pressed back accidentally, a lockingcatch M is provided. This locking-catch consists of a curved spring-plate having a slot n which is slidable longitudinally over one of the rivets c. A long projection 0 is formed at one end of the slot, and consists of a portion of the metal struck up in making the slot. A short projection or stop 7) is formed at one end of the locking-catch and is arranged to slide under the fingerbutton. The locking-catch M is slidable longitudinally in a guide-chamber 3 formed in one of the outer side-plates B.

The long projection extends through a small slot in 'the plate B on one side of the finger-button, and the curved middle portion of the locking-catch M bears against the bottom of the chamber a so that the locking-catch touches the plate A with its end portions on one side and touches the plate B with its middle portion on the other side. This enables the locking-catch to slide freely and with a prearranged resistance.

The short. projection 79 is normally arranged under the fingerbutton, and prevents it from being operated. The lockingcatch is pushed back with the thumb-nail when the knife-blade is to be opened, so that the finger-button may be operated.

\Vhat I claim isf I p The combination, with a pocket-knife provided with automatic blade-opening mechanism having a finger-button for operating it, of a safety locking-plate slida'ble longi tudinally between the inner and outer sideplates of the knife-handle, said locking-plate being provided with a laterally projecting stop at one extreme end which engages with the said finger-button and having also a projection of greater length than the said stop I I l l which projects through the same opening in theouter side-plate as the said finger-button and which affords a means for sliding the said locking-plate back and forth.

In testimony whereof I have afiixed my signature in the presence of two witnesses.

GEORGE L. MoVEY.
